BQOKMARK Filed D60. 25, 1932 V I e e/ lN'vuNTOR (May WI/J@J X TiPatented June 13, 1933 PATENT" OFFICE MURRAY WARSHAY, OF BROOKLYN, NEWYORK .IBOOKMABK Application filed'December 23, 1932. Serial No. 648,548.

The present invention relates to book marks an'daims to provide certainimprovements therein. More particularly it relates to a ;book mark whichis adapted to be either permanently associated with a book or detachablyconnected thereto and which will at all times indicate the page wherethe reader last finished reading before closing the book.

The primary object of my invention is toprovide a simple, eflicient,compact and neat book mark which can be easily applied to any bookwithout the aid of tools or supplemental securing means. Another objectis to provide a book mark which in use will not interfere with thereading of the printed page orprovide any objectionable or unsightlyprojections upon the book. Another object is to provide a book markwhich can be manufactured and sold at a low price and which may carryadvertising matter thereon and thereby'constitute an advertisingnovelty. Another object is to'provide a book mark which can bedetachably secured to any book andjcan therefore be used indefinitely.25, The foregoing and other objects of my invention which will beapparent from the detailed description which follows I accomplish byemploying a stretchable elastic element, for example, an elastic band,which is disposed in oblique relation in proximity to a corner of a bookcover over an inside face thereof, the elastic element being extensibleinwardly to engage over the pages of the book in proximity to thecorners thereof which overlie the corner of the book to which the bookshowing my invention applied thereto.

of the line 66 of Fig. 5.

Fig. 6 is a section taken along theplane Referring first to Figs. 1 to iof the draw- I 1 ing, let A indicate an ordinary book having hard orsubstantially rigid covers B, B and pages C secured or bound within theboolr covers inthe conventional manner. Detach 6 ably secured to acorner of one of thecovers and preferably to the lower right hand cornerl of cover B as viewed in Fig. 1 is a book mark comprising a cornermember D consisting of in superposed spaced relation and connectedtogether by side walls G providing a triangular pocket between the partsE and F. Preferably the triangular part E is of larger area thanthe'part F and extends a'substantial distance beyond the edge 7 of saidpart F, as best shown in Figs. 2 and 3. Outwardly beyondthe edge 7", thepart E at its opposite sides is formed with slits e which terminate attheir inner ends in small circular openings e and encircling said part Ebetween the openings e is an elastic band H which is positioned upon thepart E by being drawn through the slits e.

The corner member D may be formed 0 any desired material, for example,the parts E and'F thereof may be made of cardboard, compressed fibre orother substantially rigid material which may be suitably'covered oneither one or both: face'swith fabric, paper, leather or the likeJ so asto give to'the corner pieces a more finished and pleasing" appearance.'Preferably the pocket in the corner member is of a width to snuglyengage. over the corner of an ordinary book cover and if desired theinner surfaces of the parts E and F of said corner member may be treatedor coated to increase their frictional or holding engagement upon saidcover. If

desired the side walls G may be made of elastwo right triangular parts Eand F arranged 65 p elastic band H positioned over the inner face ofsaid cover. When so positioned the elastic band H will be disposedobliquely to the corner of the cover in proximity to said corner andsaid band will be extensible inwardly with relation to said cover. Torender the book mark operative, the elastic band H is extended to engageover the first page of reading matter immediately upon beginning thereading of a book and it will thereupon overlie the lower right handcorner of the first page and all the pages beneath it. When the readingof a page is completed and the page is turned to the left the lowerright hand corner of the page will just naturally withdraw from beneaththe elastic band and thus place the band in engaging relation over thelower corner of the next page. In reading it is natural preliminary toturning a page to engage the rear of the page at its side edge near thetop with the finger and gradually raise the page in the act of turningit, which procedure facilitates the disengagement of the lower edge frombeneath the band. It will thus be seen that the elastic 7 to alwaysindicate the last page upon which the reader was engaged in readingbefore closing the book.

Inthe embodiment of the invention disclosed in Figs. 5 and 6 the elasticband instead of being carried by a detachable member is carried by atriangular piece of cardboard, fibre or the like K provided with slitshwhich terminate inwardly in small openings k for accommodating theelastic band H in a manner analogous to that in which the band H is heldon the corner piece D.

The part K may be glued, cemented or attachedin any other manner to thelower right hand corner of the inner face of a cover B, but in orderthat the band H when Worn out or broken may be replaced by a new band aportion of the part K is preferably left uncemented to the cover fromthe edge to a line inwardly from said edge beyond the elastic band 11 asindicated by the dotted line 70 The manner of use of the invention asset forth in this embodiment is substantially the same as that describedin the preceding paragraph for the embodiment disclosed in Figs. 1 to 4:except in that the car- 7 rymg or supporting member K is permanentlyattached to the cover.

It will be apparent that where the concept underlying the presentinvention is to be applied to a book mark which is to constitute apermanent non-renewable element in a book an elastic band or stretchableelement may be secured in oblique relation to the inner face of a bookcover in proximity to a corner thereof in any desired manner.

From the foregoing detailed description it tion is susceptible, and Itherefore do not wish to be limited to the details of constructiondisclosed since the same may be varied without departing from the spiritof my invention.

What I claim is: i V

1. A book mark comprisingan endless elastic band, a support upon whichsaid elastic band is detachably mounted in definiterelation thereto andmeans for. attaching the support to a book cover to dispose theelasticband obliquely in proximity to a corner of the cover over the inner facethereof with a part of the band disposed between the support and thebook cover and apart of the V band in extensible relation to the bookcover.

2. A book mark comprising a corner member having a pocket adapted toreceive the corner of a book cover and frictionally-hold thereon, thepart of the corner member which engages over the inner face of the coverbeing slittcd inwardly at spaced points, an end- I less elastic bandengaging around said part and detachablyheld by the slits therein todispose a part of the elastic band over said corner member obliquely tothe edges of the cover, whereby said band will be extensible to engageover the corn-er of the pages of the book in proximity to the corner ofthe book cover corner to which the book mark is attached.
